Idea of the project is not new one..However i really appreciate the approach team uses. I have very strong believe this project will survive in long run!
According to ur point of view most of crypto will die?

Or what do you mean that REA will survive?
Even Vitalik Buterin told that in long run most of crypto would not exist, and only strongest one with real usecase will survive! And this particular project is one of such projects. So, yes, REA will survive
Reactor it is Probably one of the stronggest project as for now! As far as block reward is growing after few more exchange listing price will skyroket
